UNITED STATES PATENT EEICE LEONARD WELDON, OF AMSTERDAM, NEV YORK, ASSIGNOR TO THE KLAUDER-VELDON DYING lVIAOI-IINE COMPANY, OF SAME PLACE.

CENTRIFUGAL DYElN'G-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 505,49*?datedseptember 26, 1893..

Application filed February 10, 1893. `Serial No. 461.739. (No model.)

T @ZZ whom t may concern,.-

Be it known that I, LEONARD WELDON, of Amsterdam,in the county of Montgomery, in

the State of New York, have invented new and useful Improvements in Centrifugal Dyeingy rated cage also arranged axially vertical, andy ribs on the inner side of the vat extending from the bottom to the top thereof. Said ribs prevent the dye liquor `from racing and following the rapidly revolving periphery.

of the cage and cause the dye-liquor to be thrown through the perforated cover of the cage and into the center of the latter, where,

by the centrifugal force exerted on the contents of the cage, the dye-liquor iscontinuously forced through the stock or fabric without any movement thereof that might injure the stock or fibers.

The invention also consists in certain auxiliary devices connected with the machine as hereinafter more fully described and set forth in the claims.

In the annexed drawings Figure l is a vertical transverse section of a dyeing machine embodying my invention. Fig. 2 is a horizontal transverse section on line x, fr, in Fig. l, and Fig. 3 is a vertical transverse section of the dye-liquor vat.

Similar letters of reference indicate correspondin g parts.

A- represents the dye-liquor vat which is of an annular or cylindrical shape and placed axially upright or vertical. In the center of said vat is a vertical shaft -astepped in a socket -bon the bottom of the vat and passing with its upper end through a bearing -c on a bracket or spider -B which is rigidly mounted on top of the vat and rises with its center above the same as shown in Fig. 1 of the drawings. On the upper end of the shaft are mounted a fixed pulley -P and a loose pulley miP which by a belt receive rotary motionA from the driving pulley of the motor, not shown.

i In 'the vat `A and concentric therewith is an upright cylindrical cage -C- fastened to-the shaft -dso as to rtate therewith. The sides of the cage are perforated and a space 07,- is left between said sides and vertical wall of the vat. The top edge of the cage is provided with an annular shed -eewhich projects inward and isinclined toward the center of the vat where it leaves an opening for the introduction and removal of the stock or fabric to and from the cage, and over this opening is a perforated cover -O which is adapted to slide vertically on the shaft aand rests upon the shed -cwhen in its closed position.

To theinner side of the vertical wall of the vat are fastened ribs `t` which extend from the bottom to the top of said wall and may be either inclined or spirally disposed.

The top of the vat is provided with an annular deflector which extends from the vat over the top of the cage for the purpose hereinafter explained.

hdenotes the steam-pipe for heating the dye-liquor. This pipe is located on the botf tom of the'vat and bent into a circle of a diameterj somewhat greater than that of the cage so asv to bring it directly under the annular space between the cage and vat and thus facilitate the upward circulation o f the dye-liquor through said annular space as hereinafter described. The said pipe is perforated at equidistant points for the emission of steam into the dye vat, and is provided with a suitable pipe by means of which it may be connected with a steam generator.

D-fdenotes the dye-liquor reservoir from which the 'vat -A- is supplied by means of a pipe *l* leading from the bottom of the reservoir to the bottom of the vat, as shown in Fig. 1 of the drawings, said pipe being provided with a stop-cock -Z-4 by which to controlthe flow of the dye-liquor.

trepresents a suitable pump which is connected to the pipe -Z- for the purpose of returning the dye-liquor from the vat @A to the reservoir-ID-m after the dyeing operation is completed.

Ihe operation of the described dyeing machine is as follows: The cover -C- of the cage -C- is raised and the material to be dyed is introduced into the cage and the cover replaced. Then the dye-liquor which has been prepared in reservoir -D- is allowed to flow into the vat -A- by opening the stop-cock -Z. After the vat has been supplied With the desired quantity of dye-liquor the stop-cockis closed and power is applied to the driving pulley P- Which imparts a rapid 'revolution to the cage 0. In this motion the ribs prevent the dye-liquor from racing around in the annular space surrounding the cage, and the centrifugal force exerted on the dye-liquor Within the cage forces the liquor out through the perforated sides of the cage into the aforesaid annular space in which it is forced up to the top of the vat Where the deflector-flthrows 1t over the shed ,-e-, which conducts it to Ward the perforated cover -C-, through Whlch it passes down int-o the central portion of the cage to be again forced out radially through the perforated sides of the cage as aforesaid. This circulation of the dye-liquor causes the same to thoroughly permeate the material to be dyed, which latter at the same time is not subjected to any movement that may tend to tangle it or in anywise injure it. When the stock or fabric has been treated With the dye-liquor for a sufficient length of time the stop-cock -Z- is opened and the pump tset in motion to lift the dye-liquo'r out of the vat and return it to the reservo1r -D. After this has been effected the speed as to cause the surplus moisture to be expelled from the dyed stock by centrifugal force and leave the stock ready for placing it on the usual driers Without the necessity of first placing it in an ordinary rotary hydro eX- tractor.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination in a dyeing machine, of an upright cylindrical vat, a revoluble perforated cage arranged concentrically in said Vat, spirally arranged ribs located on the inner side of the vat and extending from the top to the bottom thereof, and an annular deflector extending from the vat over the cage, substantially as specified.

2. The combination of an upright cylindrical dye-liquor Vat, a revoluble perforated cylindrical cage arranged concentric in the vat,

ribs on the inner side of the vat extending from the bottom to the top thereof, an annular deiiector extending from the vat over the cage, and an annular shed on the top of the cage and inclined toward the center thereof as set forth and shown.
